Equation of Doom is a science fiction novella by Randal Garrett, first published in 1957 under the pen-name Gerald Vance.
They grounded Ramsey’s ship on a hostile planet hoping he would starve to death, so the first thing he did was give most of his money away and lose the rest gambling. Then he picked a fight with the Chief of Police and joined forces with a half-naked dream-chick who was seemingly bent on self-destruction. The stakes were big--a planet or two-but it all added up to an----Equation of Doom
What starts out as a battle of wits between an Earthman on an alien world and that world's police force turns into a chase across hyperspace with a couple of sex-objects to the primal inhuman source of all human life in the universe. And a love story.
As far as a story with a brave Earthman and evil aliens goes, this one is better than average. Good characters, and women who do more than simper.
